Red Oceans refer to the known market space, i.e. all the industries in existence today. In red oceans, industry boundaries are defined and accepted, and the competitive rules of the game are known. Companies try to outperform their rivals to grab a greater share of existing demand usually through marginal changes in offering level and price. As the market space gets crowded, prospects for profits and growth are reduced. Products become commodities, and cutthroat competition turns the red ocean bloody.
